Theseports Which serve tol'admit 'thje'fgrain, are opened and closed a valve 12', the? preferred construction offvvhicli isjhere I illustrated. Gentuy I speaking, this "valve: is semi-cylindrical in height approximately equalto tl'ieheightof the body: It is preferablji for'inedlof steel tubing and at the niarginal edges tee? invvardly extending fiengeef a, 13 liich'.fitslidingly in the greevee' tgit termed iIi'the body. 1, as best heta it rigi 4.; It i desirable that the grooves: 14 hei etted approximately 180 (16",

It tsetse desirabletliat thepo'rtion of the body coveredfiby tte'v ive befde'p'ressed slightly so that the external diameter ofthe valve is equal; toi the lexternaldiameter of the remainihg 'portion of thebody. This imparts a finished'appearance to'the device and affords protection to thetvalveby reducing the fliabilityto'injiiry by reason ofcontact with external objects. A stop 2 15, which in the present design is located inthe .point 2 andengajgesthe lower end of the valve, norholds, the valve in closed position With its upperend flt'ish withtheupper end of the body' ll, as shown in Fig." 1. The 7 Valve is "provided With a half collar 16 which corresponds to the half collar 6 and with itforms a cap for the device. A recess 17 is formed on the underside of collar 16 for receiving the ends of the fingers of the piece by which the valve may be operated. Ports or openings 18, 19, 20, 21 are formed in the sides of the valve, as best shownin' Fig. 2. :These are arranged in such manner that when thevalve is in closed positlon all of the ports in the body l-will be closed, but

will be, opened successively commencing with thefbottom port when the valve is gradually raised. fIn the design shown in the drawings, theports in the valve are of substantially'the same length and width as the ports in the body and are four in number; The ports 18 and 20 are in line with each other and the ports 19 and 21 are in line with each other, the last two ports, however, being out of. line with the first two. The alinement is such, also,that when thevalve is closed the port 18 will be out of register with'the port 7 but in line with the ports 8 and-'10. IThe ports'19 and 21 are in line with the ports 9 and 11. The lower end of port 19.ison alevel with the upper end of port 18.. Port 20 is four inches from port 19 and p'ort21'1s four inches from' port 20.

body is'opened while all of the remaining 40 ports remain closed. The inspector then rotates the device slowly back and forth through a few degrees about its longitudinal axis, the result being that the grain opposite to the open port flows into; the body of the device. -When the inspector thinks that a sufficient quantity has entered, he raises the valve to the next stage or station (in the present design four inches) and'thereby uncovers the port 8.. He then rotates the device gently back and forth: a few degrees as before, and permits the grain at this level to enter the body of the device. After sufficient grainhas entered throughthe second port in the body the third port'is opened by raising the valve four inches more, after which the fourth port may be uncovered by raising the valve anothercfour inches, and finally the fifth port is opened by rais- 1 4 ing the valve a final four inches. In order that the inspeetormay determine just how far to lift the valve each time so as to bring the ports accurately into register with each other a gage is provided, this gage consist- --'ing preferably of a rivet or. similar marker 22 fastened in the body 1 in position to cooperate with a series of rivets or other similar markers on the valve, the rivets on the valve belng located four inches apart.

By bringing a rivet on the valve to the elevation of the rivet on the body the inspector can determine that the port is open and can .determine just which port is open. After all of the ports have been uncovered in turn, and the body of the device filled to the desired level with grain, the inspector, without removing the device, lowers the valve to closed position. This traps the grain within the body of the trier, after which the device as a whole is withdrawn. The inspector then, holding the lid 1 closed, turns the device upside down and then, releasing the lid, empties the contents of the device into a bag or otherreceptacle.

As a result of this construction and manipulation, a sample is obtained from different elevations or points in the section and the inspector is certain that none of the grain which has once entered the body of the trier can escape nor can any grain from any other point in the section enter during the act of withdrawing the device from the body of grain. The inspector may thus be assured that he has obtained a fair sample of the grain as a whole, and-may also be assured that, without exercising any particular degree of skill, he has obtained his sample uniformly with the sample which he mayhave previously obtained and which he may thereafter obtain. In other words,

by the use'of this device it is possible not only to obtain a sample which is typical of the body as a whole,.but it is possible to obtain samples which are uniform with each other.

This device, to a great extent, eliminates the personal factor, and different inspectors equipped with triers of, my construction will all operate the device with practically the same results.

From the foregoing it will be seen that while the top of the uppermost port 11 in the body is forty inches from the top to the lowermost port 7, all of the ports in the body maybe uncovered by moving the valve but twenty inches. In other words, the different ports are so arranged that the valve need be moved but half the distance between the uppermost and lowermost ports in the body. 'This is of utmost importance as will be readily appreciated by those who have operated devices of this general character. Grain is usually shipped inbox cars and frequently'there is less than two feet between'the roof of the car and the top of the grain. But in my'device the valve movement is so small that it can take place even in a fully loaded car without movingthe device from the position in which the sample is taken until afterthe valve 'is-closed.

- Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. A device of the class described having a tubular body closed at the lower end and having ports arranged one above the other in said body, adjacent ports being out of alinement with each other both longitudinally and circumferentially, and a non-rotatable slide valve normally holding said ports closed, said valve having a plurality of ports arranged at different positions lengthwise of the valve, some of the ports in the valve being in line to register with some of the ports in the body as the valve is moved to open position.

2. A grain trier consisting of a tubular body having a plurality of ports one of which is out of line with another, and a valve slidable longitudinally on said body, said valve having a port in line with one of the ports of the body and out of line with another of the ports of the body.

3. A grain trier consisting of a tubular body having a plurality of ports arranged one above the other, one port being out of line with another, and a valve slidably mounted upon said body to move lengthwise thereof, said valve having a plurality of ports one above another, one of said valve ports being out of line with another of said valve ports, two of the ports in the valve being in line to register with two of the ports in the body at different points in the movement of the valve.

4. A grain trier consisting of a tubular body having a plurality of ports, some of said ports being out of line with others and in line with at least one other, and a valve slidable longitudinally on said body, said valve having a plurality of ports, one port in line with each of the ports in the body.

5. A grain trier consisting of a tubular body having a plurality of ports arranged one above the other, some of said ports being out of line with others, and, there being at least two ports in each of two given lines, a valve slidable longitudinally on said body, said valve having a plurality of ports arranged one above the other, two-of said valve ports being in line with one line of ports in the body and two other of said valve ports being in another line of ports in the body.

6. A grain trier consisting of a tubular body having five ports therein, one above another, two of said ports being in line with each other and the remaining three of said ports being in line with each other and out of the first mentioned line of ports, and a Copies of this patent may be obtained for valve slidable lengthwise of said body, said valve having four ports, two of the valve ports being in line to register with one line of ports in the body and the remaining two valve ports being in line with the other line of ports in the body.

7 A grain trier consisting of a tubular body having two sets of ports therein, one set being in one alinement and the other set being in another alinement, a non-rotatable valve slidable lengthwise on said body, said valve having a port in alinement with each line of ports in the body, adjacent ports in the body being out of alinement with each other both longitudinally and circumferentially.

8. A grain trier consisting of a tubular body having a plurality of ports therein, one above the other, said ports being arranged in a plurality of lines, considered lengthwise of the device, adjacent ports being in difi'erent lines and a non-rotatable valve slidable longitudinally on said body, said valve having a port in alinement with one of the body ports and out of alinement with another of the body ports.

9. A grain trier consisting of a tubular body having a plurality of ports therein, the lowermost three of said ports being equidistant from each other, and there being two additional ports twice as far apart from each other and from the uppermost of the previously mentioned ports as the previously mentioned ports are from each other, and a slide valve on said body, said valve having ports adapted to register with some of the ports in the body.

10. A grain trier having a tubular body,

a valve slidable along said body, and two half collars at the upper end of the device,

one half collar being fastened to the body and the other to the valve, and a lid for closing the upper end of the body.
